This formula helps your immune system to fight the enterobius vermicularis parasite infection. The FDA has not approved of these statements and you are taking this at your own risk. Again as with most of the Monastery of Herbs blends, you may test for these energetically but not actually have the infection--it means that your body needs the energy of this formula to reverse a condition you are currently experiencing. If a licensed medical porofessional has diagnosed you with this particular infection then this remedy will help to reverse the infection.
